From her first moment at Merryweather High, Melinda Sordino knows she's an outcast. She busted an end-of-summer party by calling the cops — a major infraction in high-school society — so her old friends won't talk to her, and people she doesn't know glare at her. She retreats into her head, where the lies and hypocrisies of high school stand in stark relief to her own silence, making her all the more mute. But it's not so comfortable in her head, either — there's something banging around in there that she doesn't want to think about. Try as she might to avoid it, it won't go away, until there is a painful confrontation. Once that happens, she can't be silent — she must speak the truth.
